If you had a hopelessly sub-par Indian Cent....

How would you clean it so that it looked like brand-new copper?

Let me be clear about this - I want freshly-exposed copper molecules on the surface of the coin.

Acid? Some kind of etching bath? Heavy buffing wheel?

(Let's just assume that I paid too much and bought a batch of Indian Cents that will never be salvageable.)

    If you promise not to eat them, I would tell you of some less dangerous chemicals. Some can be seen on men's undershirts.

    If you want to send them to me I will dip them in a cyanide solution, rinse in water and return them to you.

    ambro, that would be cool. What kind of pre-treatment or surface prep do you need? I am wiping the mineral oil off of them with paper towels as we speak. Do they need to be degreased with acetone for you? I'm hoping to get them real shiny so that my grandson can play with them when he gets old enough to know what an Indian Cent is. There's no residue from a cyanide dip, is there?

    Maybe I should get one of those corncob burnishing tumblers?

    Wash them good in hot soapy water. That should remove oils. No, there is no residue from cyanide when rinsed off with water. It dosent penetrate. Ive pm'd you my address.

    Keep in mind David Q Bowers says in his book that cyanide dipped coins will turn over time to a pale red color.

    These must have been someone's culls. I've culled the culls and what you are telling me is - that in a few years I will have some bent, corroded, worn and red Indian Cent remnants.

    I wonder what causes the reddening? Maybe I should acetone half of them when they come back to see if that makes any difference.

    I'm more in my element when it comes to petrochemicals, but not plating chemicals.image


    On another note, there are 2 of these that have fields that were made to look Unc but the coin is obviously worn and VG at best. I've seen this before. Does anyone know what caused that sort of effect? I have to believe that the whole coin was brightened and then the high points tarnished but the fields didn't (as much). Any thoughts on that?

    Realone, I appreciate the sentiment, and I assure you that the reprocessed coins will serve as a great contrast to the un-reprocessed coins that I'm also holding back for him to appreciate later.

    If we are both lucky, in due time he'll get to see some original D.Carr coins, some 19th Century European Crowns, some American Silver Eagles, some exquisite Large Cents, some rolls of Proof Silver Franklins, some mid-1960's Special Mint Sets, some bulk Wheat Cents saved by his other grandfather, and a couple thousand BU clad Kennedys from the early2000's. And that's only a start. Rest easy, he's going to learn about coins.image

    That's for later - in case they start to tarnish.image

    Regardless of what you do as far as a dip in either cyanide or something else, you'll end up with a dull, lifeless, more pink than copper colored coin.
    I decided to change calling the bathroom the John and renamed it the Jim. I feel so much better saying I went to the Jim this morning.



    The name is LEE!
